The NeoTech Aqua ReFleX water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. This paper explains in detail the ...
To better control chlorinous odor in tap water, we assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment. In this process, the hydrophilic neutral fraction (a major dissolved organic matter (DOM) fraction) is converted to ionic species, and these ions and ammonium ion are effectively removed during ion-exchange ...
A 4-month sampling campaign has been conducted for the monitoring of three drinking water treatment plants using flow cytometry and culture-based methods to provide information related to changes in bacterial concentration according to treatments. Flow cytometry is a fast and user-friendly technique enabling bacteria quantification and viability assessment in less than 1 hour. Specific profiles ...

The removal of suspended solids is necessary to protect membrane systems and prevent the “shadow effect” in ultraviolet (UV) treatment systems. Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculants, pre-coats or granulated media. Tests have demonstrated the complete removal of ...
Veolia Water Technologies South Africa recently commissioned a new water treatment plant for Refrigerantes Spar Mozambique Lda, a bottling plant contracted to bottle Coca-Cola and other soft drink products in Mozambique. Veolia replaced the entire water treatment plant, which treats a nominal flow of 15 m3/hour (with a peak of 20 m3/hour) of water from the municipal bulk supply, and a ...
When introducing a disinfection product which incorporates new technology, it is essential that the methods and testing used to quantify the performance of those systems follow protocols which are technically sound and which are accepted by the scientific and technical community within the industry. These protocols must be applied precisely and rigorously in order to ensure accurate, repeatable ...
Euroby Ltd, the sludge treatment specialists, are pleased to announce the signing of an agreement to be the sole UK and Ireland distributor for the unique UVOX range of water treatment systems.UVOX, as the name suggests, uses a combination of Ultraviolet and Ozone to treat infected and polluted water.Its uniqueness stems from its novel method of first producing ozone by irradiating air with a ...

The goal of this study was to further develop an incubation-quantitative polymerase chain reaction (qPCR) method for quantifying viable Ascaris eggs by characterizing the detection limit and number of template copies per egg, determining the specificity of the method, and testing the method with viable and inactivated larvated eggs. The number of template copies per cell was determined by ...
Recently there has been considerable concern in California about the detection of N-nitrosodimethylamine (NDMA) in drinking water at levels as high as 900 ppt. NDMA was found to be a carcinogen in animals and assessed as a Class 1 carcinogen. It is currently listed as a priority pollutant on the US EPA National Priorities List. California has set an 'action level' of 20 ppt for NDMA. NDMA is ...
Nitrosodimethylamine (NDMA), a potent carcinogen, is found in natural and engineered water systems. Ultraviolet (UV) treatment is potentially a useful tool for controlling NDMA at water purification plants. However, a recent study has reported that UV/advanced oxidation process (AOP) treatment may provide a source of NDMA precursors. Therefore, we investigated the effect of UV treatment on the ...
